&lt;p&gt;Also cleans up some handling around how undefined behavior&lt;br/&gt;
sanitizer finds the symbolizer, and suppresses some undefined&lt;br/&gt;
behavior in mozjs that prevented the dbtests from passing.&lt;/p&gt;

&lt;p&gt;In addition, it was recognized that we can reduce the scope&lt;br/&gt;
where we inhibit UBSANs checks for misaligned access to only&lt;br/&gt;
wiredtiger, so do that too.&lt;br/&gt;
